FRANK J. SMITH, OF MARCEL LUS, MICHIGAN.

DOOY R-SECURER.

SPECIFICATION forming part of Iietters Patent No. 521,870, dated J'une26, 1894.

Application filed January 29, I894. Serial No. 498,327. (No model.)

zen of the United States, residing at Marcel-' lus, in the county ofCass and State of Michigan, have invented certain new and usefulImprovements in Door-Securers; and I do deable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to that class of door locking bars adapted to beactuated from the outside in the locking and unlocking operation.' Thefurther purposeof my invention is to produce a door bar which can bemore readily applied to ordinary doors and with smaller expense andwhich will at the same time be simple and efficient.

To this end my invention consists of the novel features which will bemore fully described hereinafter and defined in the claims.

In the accompanying drawings: Figure 1, represents the inside of a pairof doors and a door frame surrounding them to which my improved deviceis applied; Fig. 2, an edge View of a section of the door showing'the'manner in which the operating mechanism is' constructed and applied, thedoor being represented in dotted lines, and Figs. 3 and 4 views ofdetails. r

The reference letter or represents one of a pair of doors and b theframing around the doors.

0 represents the door bar which is adapted to extend across the back ofthe doors. One end of this bar is pivoted to a cleat d attached to oneside of the door, and the-other end of the bar drops down into an openclasp or keeper e on the frame I) surrounding the doors. The free end ofthe bar is raised and lowered by means of an eccentric f and thiseccentric is turned or rotated by a spindle g passing through the door aand having on its outside end an operating handle h. The ec-.

centric is provided with a rim f wide enough for the reception of theedge of the bar and this rim is provided with an annular flange f whichoverlaps the side of the bar-a short distance and keeps it from slipping0E. The

. spindleis fixed to the eccentric by passing through a hole made inanembossment f in which it is locked by a set screw f". The

spindle revolves in a pair of bearings k and t bolt m located over thespindle in such juxtaposition that the bolt when thrown out in lookingadjustment will extend over a vertically extending arm 0- fixed to thebar. This arm may be given any suitable form that will enable it toengage or be intercepted by the bolt m when thrown out to project beyondthe casing of the look as shown in Fig. 1. Preferred form, however, ofconstructing the arm is to make it of flat metal bout with a shoulder cto fit over the top of the bar and an inwardly extendinglip c on itsupper end adapted to engage the bolt. It will be observed from thepreceding description, that when it is desired to lock the doors thefree end of the bar can bedropped down into the keeper 6, the largerportion of the eccentric f havingbeen turned downward so that the upwardprojecting arm 0' on the bar will lie below the bolt m. Now when thebolt is thrown outward over said arm by means of a key introduced fromthe outside, the bar will be locked down and the doors cannot be opened,because it will be apparent that any effort to raise the bar will causethe arm 0' to come in contact with the locking bolt and thereby preventthe bar from being lifted out of the keeper. To open the door all thatis necessary to be done is to throw back the bolt ICC exact constructionherein shown but consider myself entitled to all such variations as comewithin the spirit and scope of my invention.

secure the latter from movement, substantially as described.

2. A door fastening comprising a cross bar pivoted at one end, a keeperto receive the other or free end of the cross bar, a knob operated camadapted to engage with the under side of the bar and lift the free endfrom the keeper, and a key operated lock located above and adapted tohave its bolt engage with the upper side of the cross bar, substantiallyas set forth.

3. The herein described door fastening com prising a cross bar pivotedat one end, a keeper to receive the free end thereof, an arm projectedfrom the cross bar, a key operated lock adapted to have its boltprojected across the path of the said arm, a knob spindle having aflanged cam to engage with the cross bar, 1

and bearings for the ends of the spindle having sleeves which are letinto the door, the inner bearing having an escutcheon and plate for thecross bar to rub against in its movements, substantially as described.

4. The combination in a door fastening device, a pivoted cross-bar, akeeper adapted to engage the free end of said bar, an eccentric forraising and lowering said end, an arm on the bar, and a lockprovidedwith a bolt adapted to be thrown into the path of said arm tointercept the lifting action of the bar, substantially as described.

5. The combination with a pivoted doorbar, of a keeper adapted to engagethe free end of the bar, an eccentric located on the inside of the door,an actuating spindle extending through the door and to which theeccentric is fixed, an upwardly projecting arm fixed to the bar, and alock provided with a bolt adapted to be thrown out within the range orpath of said arm to prevent the bar from moving out of its keeper in themanner and for the purpose substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
